Application July 9, 1941, Serial No. 401,621 claims. (ci. 19-140) Myinvention relates to the class of devices above mentioned, andan objectof my invention, among others, is the production of an underclearer rollthat shall maintain its shape under all conditions to which it issubjected in use; and a further object of the invention is theproduction of a device of this type that may be readily produced in acomparatively simple manner and that will be particularly effective inthe results produced by its operation.

Forms of underclearer rolls embodying my invention and in theconstruction and use of which the objects herein set out, as well asothers, may be attained are illustrated in the accompanying drawing, inWhich- Figure l is a side view of an underclearer roll embodying myinvention.

Figure 4 is a view similar to Fig. 2 but illustrating a little differentstructure. l Figure 5 is an end View of the latter forml of roll.

Figure 6 is a view in central lengthwise section of one end of myunderclearer roll embodying a little different form of construction.

Figure 7 is a view similar to Fig. 6 but trating another modication. y

inus- Figure 8 is an isometric view of one end of the roll illustratedin Fig. 7.

Figure 9 is a view similar to Fig. 8 and illustrating the manner kofapplying the Cellophane wrapper.

Figure 10 is a view similar trating a modification.

Figure 11 is a View illustrating the manner of forming the outercovering from an'extension of the paper wrapper only Wound several timesaround the roll to complete the outer jacket.

Owing to the diniculty in showing the sheets in section, due to thethickness of said sheets, they are not separately shown in the sectionalviews herein or in the end view, Vlout it will be understood that asotherwise shown in the figto Fig. 7 but illusures the sheets lie oneagainst the other and are wound several times around the roll tocomprise the parts specifically referred to.

The extreme conditions as to heat and moisture in the rooms in whichunderclearer rolls are used are such as to strain the ability of therolls to withstand the harmful effects and unless such rolls are mostefciently constructed and in a sential that the rolls shall preservetheir true formA and shape in order to prevent any spaces between themand the rolls in connection with which they are used. It is thereforeessentialV that the underclearer rolls shall be most rigid and thattheir rigidity shall be preserved, and my invention illustrated anddescribed herein enables rolls bearing these characteristics to beobtained at comparatively little expense.

Up to the present time it has been the universal custom to employunderclearer rolls made of substances and in a manner to withstand to acertain degree the harmful effects of heat combined with moisturehereinbefore referred to. The construction of such rolls has involved-considerable expense and it has not been appreciated that the lifeofsuch rolls could be materially prolonged. This appears to have been acase in which, as in some other arts, the rolls in use were allsufficient and no thought has been given to any improvement, doubtlessfromtheff'act that' no improvement was thought to be possible ornecessary. No attempt has heretofore been made to improve the structuresparticularly by protecting the rolls from contact with moisture by theuse of an ensheathing material whereby such moisture is prevented fromgaining entrance to the material composing the core of the roll.

I have demonstrated that bythe use of'such an encasingmaterial cheapsubstances such as wood of an inferior grade and othersubstances may beemployed and when encased in a material impervious to moisture suchrolls may be used indefinitely and for periods much longer than the moreexpensive rolls now in common use, and while preferably I employCellophane as a covering or ensheathing material other substances whichwould be impervious to moisture will be found to accomplish my purpose.

` In order to eiect my purpose in the production of a roll involvingcomparatively little expense wood is found to particularly fulfill therequirements, although other material may beemployed and the inventionwill be vfound to well apply to such rolls. My invention enables suchmaterials to be used whitout being affected by the extreme heat combinedwith moisture conditionsof the rooms in which they are used, the rollsbeing encased in a manner to prevent the moisture from gaining access tothe bodies or cores of the rolls while the surfaces are maintained in amost satposed in whole or in part of Cellophane or other4 In theparticular arrangement shown in Figs. 2 and material or materialsimpervious to moisture.

3 this sheath is composed of several sheets of Cellophane and paper, onesheet 'of eacliof said -f materials being shown for the purpose ofillustra'- tion herein, said sheets being' placed in contact one withthe other [and then wound upon theroll. While the exact arrangement isnot material, as shown the sheet 8 of Cellophane is placed next to theroll 1 at the'beginning of the winding operation and the sheet 9 ofvpaper is placed next to the Cellophane sheet as shown in Fig. 2, itbeing desirable that the sheet 8 of Cellophone shall extend at leastonce completely around the roll and as many more times as may seemexpedient. The two sheets woundtogether as just explained comprise asheath I0 which encloses the rolls. 1 and this sheath is enclosed in ajacket II Which may be composed of a spearately formed tube of paper orother Vsimilar material, or this jacket may be formed by making thepaper sheet longer than the Cellophane sheet and windingit severaltimes, independently `of the Cellophane sheet, around the roll tocomplete its formation as hereinbefore shown and described.

To protect the end` of the body 1 from rthe entrance of moisture a capI2 of materialimpervious to moisture, as vulcanized.. rubber .or metal,is iitted, over the end of the core 1 and has a ange which is extendedinwardly to penetrate the end of the sheath and-jacket, as shown in Fig.2 wherein it is forcefully entered between the jacket VIl and the core 1and into contact with the endof the sheet I0. This cap may be providedwith ribs I3 to prevent the cap from turning and a journal I4 comprisingthe end of a pin I5 driven` into the end of the core 1 is provided forthe purpose of rotatably mounting the roll in suitable bearingsthereforin a manner that will bereadily understood. f *l I In that form of thedevice shown inFigs. 4 and 5 the body or core I6 of the roll is composedof paper formed in any suitable manner, as by winding a sheet or sheetsseveral times around the structure to obtain the desired thickness, orit may 4be formed in any manner common tothe way of making paperrolls.This structure is similar to that shown in Fig. 2 with the exceptionthat the core I6 is formed with recesses I1 in its ends, a plug I 8,Vpreferably of wood orsimilar material, being secured in said recess.The pin I5, journal I4, and cap I2. may be of the same nature as thatshown in Figs. 2 and 3v and the structure is enclosed in a jacket II asshown in said figures. y

In the roll as yshown in Fig. 6 the core or body 1, the sheath I0, andpin I5, journal I4 and jacket Il are formed in substantially the samemanner as described and shown with respect to Figs. 2 and 3. A ange I9is formed on the pin I5 ina manner similar to that shown in Figs, 2 and4, this flange abutting squarely against a filling 20 which may becomposed 0I gli-1.8, Shella,

or other material impervious to moisture this to protect the end of thebody or core 1, in a manner that will be readily understood. The deviceshown in Fig. 7 is similar to that shown in Fig. 6 with the exceptionthat the end of the sheath I0 which is composed of paper and Cellophane,or even of Cellophane alone, is folded over the end of the core as at 2|to complete the sheath I0 and therebyprotect the core as particularlyshown in Fig. 8.

v The structure shown in Fig. 10 is quite similar to that disclosed inFig. 6 with the exception that the entire jacket 221s composed of awinding'of sheets of Cellophane and paper, as hereinbefore described,and a filling 23 of glue, shellac or'similar material impervious tomoisture is interposed between the end of the body 1 and the flange I9on the pin I5.

In that form of the structure shown in Fig. 11 the body or core 1 isenclosed in a sheath I0 formed of a winding of sheets of Cellophane 8and paper 9 and the jacket, IWI is formed by several windings o f thesheet 9 of paper which is made considerably longer than the sheetorsheets of Cellophane so hthat'I as the Cellophane sheets terminatewithin the paper winding the latter is continued and wound several timesaround the roll to complete the jacket II asV hereinbefore explained inconnection with Fig. 2. It is to be noted that the core 1 whether-Lofwood orv other material is so enclosed within the jacket comprising theCellophane and other material that the core may be removed 'when it hasoutlived its purpose and a new core substituted, thus enabling thejacket to be used indefinitely.

In accordance with the provisions ofthe patent statutes I have describedthe principles of operation of my invention, together with the devicewhich I now consider to represent the best embodi-m'ent thereof, vbut Idesire to have'it understood that the device shown is only illustrativeand thattherinvention maybe carried out by other means and applied touses other than those above set out.
